Hot on the heels of the "ornamental design" patent covering its original iPhone and iPod touch, we've got a second USPTO patent granted to Apple covering what looks to be the more curvaceous iPhone 3G and 3GS. Jonathan P. Ive and Steve Jobs are among the inventors credited with the usual list of references including the LG KE850 Prada and Meizu M8 look-a-like devices. Don't get too hung up on the missing "home" button -- a US design patent covers any device "substantially similar" to the images above. What that means only a judge can say.
